SELF-ACTING MULE FOR SPINNING.

SPECIFICATION forming part Of Letters Patent NO. 645,928, dated. March20, 1900. Application filed September 29,1899. Serial No. 73Z,-094. (N0model) To all whom it may concern.-

Be it known that 1, JAMES PICKFORD, a subject of the Queen of GreatBritain, residing at 12 Vigo street, Lees road, Oldham, in

the county of Lancaster, England, have i11- vented' new and usefulImprovements in Self- Acting Mules for Spinning, (for which I have madeapplication for a patent in Great Britain, No. 20,150, bearing date the23d day of September, 1898,) of which the following is a specification.

My invention relates to improvements in self-acting mules for spinning,and has for its object to simplify and render more reliable in actionthe means which operate the ratchetwheel click on the winding-plateemployed upon the tin-roller shaft. I attain this object by themechanism illustrated in the accompanying two sheets of drawings, inwhich- Figure 1, Sheet I, is a vertical section through the square ofthe mule; and Fig. 2, a plan of a portion of Fig. 1, showing. myimprovement applied. Fig. 3, Sheet II, is a vertical section through thesquare of the mule; Fig. 4, a plan, and Fig. 5 a side view, of amodification of the invention.

Similarletters refer to similar partsthroughout the several views.

In carrying out myinvention and referring to Fig. 1, a is the square, I)the tin-roller shaft, 0 the ratchet-wheel click, (1 the winding-platecarrying the ratchet-wheel click 0, e the winding-on ratchet-wheel, fthe winding-click spring, 9 the peg on the windingclick, it the cone orcam, t the faller-locking or fish-mouth lever, 7c the boot-leg, Z thefallersector, and Z a portion of the frame of the head-stock of themule, which parts so far are old.

Upon the tin-roller shaft 6 I employ the winding-click-locking lever m,which I'actuate from any suitable part of the mule, effecting thelocking of the faller-for instance, from the boot-leg 7cby means of thearm n, one end of which is jointed to the inner end of thewinding-click-locking lever m and the other end fixed to a lever 0,connected to the stud p of the locking or fish-mouthed lever t', and bythe arm 9, connected to the latter and the boot-leg 7c. Thewinding-click-locking lever on when moved oscillates on the tinrollershaft 1) and causes, through the medium of the click-spring f, which ismounted in a groove 7*, formed in the boss 8 of the ratchetwheel windingclick locking lever m, the click 0 to engage with the winding-onratchetwheel 6, as is well understood, before the commencement of theinward run of the carriage and as shown in Fig. 1.

Upon the boss 3 of the ratchet-wheel or winding-click-locking lever m Imount the winding-click-holding-out cone or cam h, which is operated bythe forked lever t, placed under the influence of a spring u, securedthereto and to the square 0. of the carriage, which spring causes thefork-lever t to slide the cone or cam h against the peg g of the ratchetor winding-click c, and thereby pre vents the latter from engaging withthewind= ing-on ratchet-wheel 6 until it has been re-' leased by thewithdrawal of the cone or cam h. The end of the ratchet-wheel orwindingclick-locking lever m I form or furnish with a projection orincline 1;, adapted to operate the cone or cam fork t. The oscillationof the click-locking lever 0% simultaneously liberates and brings, bymeans of the said fork levert and cone or cam h, the clickc into gearwith its ratchet-wheel e, the position of the click-locking lever mshown in the drawings being that when the click has been liberated andbrought into gear with the winding-on ratchet-wheel 2.

By the use of the cone or cam h I prevent the winding-click c from goinginto gear be fore the proper time, and by means of the click-lockingdevice described I secure the engagement of the said click with the winding-on ratchet-Wheel 2, thereby preventing the winding-click 0 goinginto gear before the locking of the faller and insuring its promptengagement when required on the lock of the faller and before thecommencement of the inward'run of the carriage.

According to a modification of my invention I may dispense with theaforesaid lever 0, Fig. 1, and form the boss 3 of theratchetwheel-click-locking lever m (see Sheet II) with an arm to, whichI connect by means of a link a: to a double-ended lever y, fulcrumed tothe bracket .2 and connected by a rod :12 to the stud p of thefaller-locking or fish-mouth lever 15.

In order to render my improvement ap plicable for mules wherein the tinroller is adapted to rotate right or left, I employ upon theratchet-wheel-click-locking lever m two projections or inclines o o inlieu of only one, and the arm 10 I form withtwo bosses w w and the levery with a stud-hole y, so that the link a: may be employed at either sideof the fulcrum of the lever y (see more particularly Fig. 4) and one orthe other of the said projections or inclines 2: v thus brought intooperation with the fork-lever 25 in accordance with the direction inwhich the tin roller revolves.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In self-acting mules, the combination of the tin-roller shaft, thewinding-on ratchetwheel thereon, the winding-plate also on said shaft,the click on the winding-plate, and having the pin g, the cone h movablelongitudinally of the tin-roller shaft and arranged to engage the pinonthe click, the fork-lever for operating the cone, and a click lockingand liberating lever pivoted on the tin-roller shaftand having a grooveformed in its boss for the reception of the click-spring with its endterminating adjacent to the end of the fork-lever and provided with anincline on its end, the incline on said end for operating the fork-leverand means for operating the click-locking lever when the faller islocked, substantially as described.

2. In self-acting mules the winding-ratchet e, the winding-click, theclick-locking lever m furnished with two projections orinclines 12,1 andhaving an arm 10 with two bosses w w in combination with a rocking lever3 and link x, the latter being adapted to connect the said click-lockinglever with the said rocking lever on either side of the fulcrum of thelatter so as to bring one or the other of the said projections orinclines into operation all substantially as and for the purpose setforth.

In Witness whereof I have hereunto set my hand in presence of twowitnesses.

JAMES PIOKFORD.
